带电显示器
Voltage Detecting Indicator
Integrated capacitive voltage detecting system shall includes the coupling dielectric ,the capacitive coupling electrode and a built-in voltage indicator with testing point. The device CVD series shall includes an indicating element and the connecting lead with voltage limiting device.
The voltage indicator CVD series is used in medium voltage switchgear systems exceeding 1KV connected to capacitive coupling electrodes.
Phase comparator CVD/TC-R is designed for comparing two phases and/or detection of primary voltage via capacitive voltage dividing system.
CVD*-IL/IX系列户内高压带电显示器配合容性高压传感器构成高压带电显示装置，用于显示高压线路带电状态。具有闭锁功能的显示器CVD*-IL系列可同时闭锁高压电气设备，以防止电气误操作，误入带电间隔。
CVD*-IL/IX系列户内高压带电显示器配合容性高压传感器，可用于1KV以上的中压开关柜系统。
验电/核相器CVD/TC-R显示器CVD*-IL/IX上的验电端口，可显示高压线路是否带电或核对两台电气设备上的相序。
